The apparatus further comprises means for lifting and moving the baffle support arm and a latch means for changing the baffle holders.

Abstract: A control circuit for an apparatus for inspecting objects, such as glass bottles and the like, for defects includes an interface circuit connected between a source of data signals and means for processing information obtained from the object. The interface circuit receives the data signals, typically in digital series form, and includes a latch for storing one of the digital signals, a pair of adders, and a storage means for a plurality of threshold signals. Each data signal is compared to the preceding data signal stored in the latch in one of the adders to generate a difference signal representing the difference in magnitudes between the two signals. Each difference signal is compared with a selected one of the stored threshold signals in the other adder to generate an event signal representing the difference in magnitudes between the two signals.

Abstract: Apparatus including a continuously traveling conveyor belt upon which containers which have dissimilar opposed panels are carried in line singly through a zone where the containers are separated from each other a small amount and then are permitted to pass in single line through the orienting device which, in those cases where the container is properly oriented, will permit the container to travel undisturbed through the orienting area. In the event the container arrives at the orienting position with its panels in the wrong directions, the container will be turned through 180.degree.

Abstract: A registration control circuit for a printed label cutoff machine controls both the location of the cut by performing a phase adjustment and the length of the individual labels by performing a base speed adjustment. A strip of labels have eyemarks printed thereon for defining the location at which the individual labels are to be cut. An optical scanner is positioned adjacent the labels and generates a scanner pulse upon detection of an eyemark. The control circuit includes a setup control for automatically running the machine into registration from an initial setup position. The setup control functions to generate a reference pulse a predetermined distance before the scanner is expected to see an eyemark. When the eyemark is detected within a designated window area the control utilizes the scanner pulse and the reference pulse to calculate the phase error for each label and generate a phase correction signal proportional to the actual phase error.

Abstract: The machine has a plurality of individual glassware forming sections each having a plurality of glassware forming mechanisms and means for distributing gobs of molten glass to each of the individual sections in an ordered sequence over one machine cycle consisting of a fixed number of clock pulses by cycling the forming mechanisms in a predetermined sequence of forming steps. Each individual section has an electronic control system responsive to each clock pulse for providing a load signal and forming signals to actuate the forming and a circuit for providing a gob load signal in response to a load signal from any one of the control systems and means responsive to the absence of a gob load signal for deflecting a gob from being distributed to an individual section.

Abstract: This disclosure relates to apparatus for forming tubular sleeves of heat-shrinkable cellular polymeric material from a predecorated web or roll. Predecorated body labels having precisely presized dimensions are formed from a web or roll on a turret type machine by serially winding rectangular thin sheet blanks of such material on cylindrical mandrels and overlapping the ends of each blank prior to seaming the same to make a presized tubular sleeve. The sleeve seam is formed by thermal fusion using an improved heated sealing bar which is heated during its retraction into contact with an improved annular metallic support ring having a series of internal cartridge type heaters therein. The ring is adapted to rapidly heat up and accurately control the heating of the sealing bars to a precise uniform temperature for improved sleeve making. The sleeves are then applied serially to either glass or plastic containers.
